Free Surface Water Tunnel (FSWT)

Description:
The Free Surface Water Tunnel consists of the intake plenum, the
test section and the exit plenum. The intake plenum starts with a
perforated pipe that sprays jets of water into the settling
chamber. The flow continues through a set of honeycomb
straighteners and anti-turbulence screens, and then through a 4:1
contraction. The intake plenum is followed by the test section, 24
in. x 18 in. x 108 in. (0.46m x 0.6m x 2.7m), which has glass on
the sides and bottom, with the top open. After the test section,
the flow enters the exit plenum, which consists of a set of
horizontal and vertical turning vanes, followed by a [HTML_REMOVED]hopper[HTML_REMOVED]
connecting to the return piping. Primary customers are military
science and technology development programs.Capabilities:
